After you’ve completed composing your story, you’ll have the opportunity to attach a photo. Selecting “Browse for photo file” will open the photo features on your device. You can take a new “selfie” photo, or browse your photo library for an existing photo. Depending on your device, the photo you take may not save to your library. Using an existing photo or taking a new photo ahead of time will ensure that your photo is saved to your photo library, and you may have the opportunity to select a file size for your attachment.
